(Based on "Yep, MORE nanos in the bush" by HappyUke)
Nano containers are hard to find already, for this cache you need to find four virtual ones plus a physical final one.
These nanos on the map are water towers or water reservoirs. I found nine locations on the map of the Sutherland Shire with water towers or reservoirs, so you have enough to chose from!
Once you have found all four of them, determine the coordinates of the middle of the nano and use an intersection tool to determine the crossing of the lines.
- Mathematically: You can use this one for example.
- Creative: Draw the crossing lines in Google Earth Pro.
If the intersection is on a parking lot, then you are close and you can find the last nano: Look for it at the No Parking sign. Good luck!
